Investigators are looking to identify a man suspected of robbing a Troutdale and a Gresham business on Monday.

The Multnomah County Sheriff's Office, along with Troutdale police, are investigating an attempted robbery at 7:23 p.m. at the Plaid Pantry, at 246 W. Columbia River Highway in Troutdale. A man implied he had a gun in his jacket pocket and ran when the clerk refused to give him money.

Moments later, at 7:56 p.m., the same suspect robbed the Orient Country Market, at 29822 S.E. Orient Dr. in Gresham. The man implied he had a gun and fled with about $100 in cash.

The suspect was described as a male in his early 20s, skinny at about 170 pounds, large nose, with acne at the bridge of his nose and on his cheeks, about 5 foot 10 to 6 feet tall and wearing blue jeans. He wore gloves in both cases.

A $1,000 reward is being offered for information leading to the arrest and conviction of the suspect in these robberies.
